I am just curios

Could you describe what is on this coin (the side without the Queen Elizabeth II)

N#217737

and then propose proper tags?

This is just to see if I am not able to properly understand the picture

Im not sure what you're asking.

If you're asking whats on the coin, the description on the page is more than adequate.

"Captain Feathersword, Wags the Dog, Dorothy the Dinosaur & Henry the Octopus depicted in colour behind a yellow blob."

 Choice for tags from: 

Fictional character 

 and that seems to be about it from the list. 

 Took me a while but I made this one picture, of all current tags, and highlighted yours. 

May be others on there to be used … 

The Wiggles are a childrens television show, aren't they?

From that list of tags, I agree that Fictional Character is the only one that seems to apply.

maybe - theatre ( television show should be theatrical)

the current tags are pretty much good

"Prehistoric animal

• Dog or canid
• Marine invertebrate
• Theatre"

considering that all of these things are represented in some form on the coin. 

fictional characters is a tag that could be added if that tag exist. otherwise the tags are fine to me

The Wiggles do have some good beats.
